A patient who had previously undergone a subtotal gastrectomy was scheduled for removal of a brain tumor under general anesthesia. Anesthesia was induced with lidocaine and propofol with rocuronium for neuromuscular blockade. She had fasted for 10 hours, but after mask ventilation, she aspirated gastric juice and materials. The oral cavity was suctioned promptly and the trachea was intubated. Intraoperative high FiO2 and dopamine were administrated to maintain the oxygen saturation and blood pressure. She received postoperative ventilatory care in the intensive care unit for 2 weeks. An upper gastrointestinal series and fiber endoscopy were performed but she had no obstruction and reflux esophagitis except delayed passage of the contrast media. She had no risk factors for pulmonary aspiration. As in this case, patients with previous gastrointestinal surgery should be considered preoperative workup for GI motility or pathology, and adequate premedication.
